Abstract
Studies have been performed examining the effect of the geometric standard deviation (1nσ) of lognormal distributions of tungsten powders on the resulting microstructure and sintering behaviour. Lognormal powder size distribution with controlled mean size and 1nσ were produced by classifying bulk powders into narrow size cuts and reblending in the desired proportions. Sintering behaviour of the blend was evaluated by comparing densification rates of samples with different 1nσ values at each of several constant mean particle sizes. Specimen microstructures were evaluated in detail to better understand the observed sintering behaviour.
